  • Method for blocking high frequency nerve stimulation
    Patent number: 4298608
    Abstract: 1,4-Disubstituted-1,2-dihydro-1,3,5-triazin-2-ones are used to block conduction of high frequency nerve impulses by selectively acting to substantially completely block high frequency impulses without significantly blocking conduction of a single impulse. The effect is reversible when the drug is withdrawn.
